The present study aims at the assessment of genetic diversity by use of ISSR primers (ISSR03, ISSR16, UBC820, UBC823, UBC834, UBC848, UBC857, UBC866, UBC874) and phytochemical diversity by HPTLC method in 17 population of <em>V. jatamansi</em> (V1–V17) from different regions of Himachal Pradesh. Total documented polymorphic bands were 81 respectively. Polymorphism percentage ranged from 25 % to 100 %. Among all populations studied, the maximum yield of valerenic acid was recorded in Hatu population (0.83 ± 0.01 %). High intra-specific variability was observed. Narkanda population exhibited the highest genetic variability (Shannon's information index, I = 0.43; Nei's genetic diversity, h = 0.27), indicating a genetically robust and stable gene pool. Conversely, accessions from Tisa and Hatu displayed markedly low genetic diversity (I = 0.16–0.18; h = 0.11), suggesting restricted allelic variation and a heightened risk of genetic bottlenecks. High altitude plants showed a high percentage concentration of valerenic acid. Thus, results of present study can be used as paramountly significant tool to assess the presence, quality, purity, and efficacy of the valerenic acid in <em>V. jatamansi</em> and genetic diversity assessment by ISSR markers.

In contrast, the exudates caused mild and non-significant effects, including both weak inhibition and stimulation.

High-performance liquid chromatography identified the toxic amino acid mimosine as a key component of the root extract, with little to no presence in the exudate.

Therefore, although <em>L. leucocephala</em> roots contain toxic metabolites, they are not released into the rhizosphere in significant amounts.

Quantitative analysis revealed significant variations in nutritional parameters such as crude fat, fiber, protein, and carbohydrate contents across different floral parts and altitudes. Inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis revealed that <em>B. ceiba</em> is a rich source of calcium (91.65–314.35 mg/kg) and phosphorus (2407.34–5942.51 mg/kg).

Gas chromatography-mass spectrometry (GC-MS) analysis of methanolic extracts from high-altitude samples identified 24 bioactive compounds, including terpenes, fatty acids, ketones, alkanes and fatty acid esters, which are common in all floral parts. These compounds are well-known for their antioxidant, anti-inflammatory, and other biological activities.

In its stems, the galling insect <em>Dasineura peumi</em> (Diptera; Cecidomyiidae) induces severe anatomical disruption and alters the chemical composition and antioxidant activity of alkaloids and phenolic compounds. However, it remains unknown whether these alterations propagate systemically to the leaves. We hypothesized that this insect also triggers systemic changes in leaves from galled branches, potentially affecting their anatomical structure, biochemical composition, and antioxidant potential. To test this hypothesis, leaves from galled and nongalled branches were analyzed via quantitative assays for phenols, flavonoids, and antioxidant activity, complemented by histochemical staining, anatomical observations, and cytometric comparisons. Our results demonstrated that the structural damage observed in stems does not extend to the leaves, even when they develop above the affected stem region. Nonetheless, both the composition and concentration of polyphenols, including flavonoids, were significantly altered but in contrasting patterns: the total polyphenol content increased in leaves from galled branches, whereas the flavonoid content decreased. Furthermore, stem gall induction modified the profile of the polyphenol subclasses and individual compounds in the leaves. Despite these biochemical shifts, the antioxidant capacity of the leaves remained stable, suggesting a compensatory balance in the antioxidant system of <em>P. boldus</em>. These findings highlight the ecological role of secondary metabolites in mediating plant–insect interactions, providing novel evidence that insect-induced galls on <em>P. boldus</em> stems trigger systemic alterations in the phytochemical profile of the host plant.</div></div>","PeriodicalId":8799,"journal":{"name":"Biochemical Systematics and Ecology","volume":"125 ","pages":"Article 105197"},"PeriodicalIF":2.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145622534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
